Since I make my own calls, I have experimented with many different elements in constructing calls, including constructing all-proph calls of varying configurations. In proph calls in particular, I have seen a great deal of variation in sound quality from call to call. I have made some that sound great,...and I have made some that I thought would sound great that ended up being terrible. That may or may not be the case with other call makers, but I suspect it might be a common problem.
The obvious issue with mouth calls is that they cannot be pre-tested for sound quality. The guy that buys the call is the one who finds out if it is any good or not,...and nobody else is probably going to find out if the problem is in the call,...or the caller.
As I stated before, I have found that most mouth calls can be modified to sound better,...and sometimes greatly so,...from the product as it comes in the package from the maker. That holds true for almost all of them, including the all-proph versions. Having said that, there are some mouth calls that are just destined to be duds. At some point we all just have to accept that and move on.
